CVE-2024-48793 identifies a vulnerability in the INATRONIC com.inatronic.bmw firmware version 2.7.1, specifically within its firmware update process. This flaw allows a remote attacker with local network access to extract sensitive information from the device without requiring any privileges or user interaction. The vulnerability is classified with a CVSS 3.1 base score of 5.9, reflecting a medium severity level. The attack vector is local (AV:L), meaning the attacker must be on the same local network or have local access to the device's update interface. The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as indicated by the CVSS vector (C:L/I:L/A:L). No known exploits have been reported in the wild, and no patches or remediation instructions have been released by the vendor at this time. The lack of detailed affected version information and absence of CWE identifiers limits deeper technical insight, but the core issue revolves around insecure handling of firmware update data, potentially exposing sensitive firmware or device information. This could facilitate further attacks or unauthorized firmware manipulation if combined with other vulnerabilities. The vulnerability affects embedded systems running the INATRONIC com.inatronic.bmw firmware, likely used in automotive or industrial control environments.

The vulnerability poses a moderate risk to organizations deploying INATRONIC com.inatronic.bmw firmware, particularly in automotive or embedded device contexts. An attacker with local network access could extract sensitive information during the firmware update process, potentially exposing device internals or cryptographic material. This information disclosure could be leveraged to craft more sophisticated attacks, including firmware tampering or denial of service. While the attack requires local access and no privileges, the impact on confidentiality, integrity, and availability is non-negligible. Organizations relying on these devices may face risks to operational continuity, data privacy, and device trustworthiness. The absence of known exploits reduces immediate risk, but the vulnerability could be targeted in environments where local network access is easier to obtain, such as manufacturing plants, service centers, or poorly segmented networks. The medium severity rating suggests that while the threat is not critical, it warrants timely attention to prevent escalation or chaining with other vulnerabilities.

Organizations should implement strict network segmentation to isolate devices running INATRONIC com.inatronic.bmw firmware from untrusted local networks and users. Access to the firmware update interface should be restricted using firewalls, VPNs, or access control lists to limit exposure to authorized personnel only. Monitoring network traffic for unusual firmware update requests or data exfiltration attempts can help detect exploitation attempts early. Since no patches are currently available, organizations should engage with the vendor to obtain updates or advisories and apply firmware updates promptly once released. Employing secure update mechanisms such as cryptographic validation of firmware and encrypted update channels can reduce risk. Additionally, conducting regular security assessments and penetration testing on embedded devices and their update processes can identify similar vulnerabilities proactively. Documenting and enforcing strict operational procedures around firmware updates, including physical security controls, will further reduce the attack surface.
